One day, in line at the company cafeteria, Joe says to Mike behind him,
'My elbow hurts like ****. I guess I'd better see a doctor.'

'Listen, you don't have to spend that kind of money,' Mike replies.

'There's a diagnostic computer down at Wal-Mart. Just give it a urine sample and the computer will tell you what's wrong and what to do about it.

It takes ten seconds and costs ten dollars . . . A lot cheaper than a doctor.'
So, Joe deposits a urine sample in a small jar and takes it to Wal-Mart.

He deposits ten dollars and the computer lights up and asks for the urine sample. He pours the sample into the slot and waits.

Ten seconds later, the computer ejects a printout:
'You have tennis elbow. Soak your arm in warm water and avoid heavy activity. It will improve in two weeks. Thank you for shopping @
Wal-Mart.'

That evening, while thinking how amazing this new technology was, Joe began wondering if the computer could be fooled.
He mixed some tap water, a stool sample from his dog, urine samples from his wife and daughter, and a sperm sample for good measure.

Joe hurries back to Wal-Mart, eager to check the results. He deposits ten dollars, pours in his concoction, and awaits the results.

The computer prints the following:
1. Your tap water is too hard. Get a water softener. (Aisle 9)
2. Your dog has ringworm. Bathe him with anti-fungal shampoo. (Aisle 7)
3. Your daughter has a cocaine habit. Get her into rehab.
4. Your wife is pregnant. Twins. They aren't yours. Get a lawyer.
5 . If you don't stop playing with yourself, your elbow will never get better!

Oh you're the one up in the tree? I use binoculers myself, and a heat sensing camera so I can see what's going on when she closes the curtains... A little expensive but... Actually that reminds me. Where's my money man? You got time to post on forums and you aint got my money?
